Actuator DTC Detection Test

ACTUATOR DTC DETECTION TEST

The Actuator DTC Detection Test:
- is actuated with a scan tool.
- supplements the continuous diagnostics on the actuator drive system.
- monitors for shorted actuator circuits allowing service to easily diagnose and troubleshoot up to three simultaneous shorts. Shorted actuator circuit faults (Control Circuit High or Control Circuit Low) will only display after running the Actuator DTC Detection Test.

After repairing each DTC, cycle the ignition switch, and then run the Actuator DTC Detection Test again to ensure that no new DTCs exist. If multiple DTCs are present, beginning with the common circuit, diagnose and repair all short high faults and then short low faults. When the test returns passed, clear all faults and run the Actuator Calibration function as a final check of system health.
